IMPROVED APPARATUS FOR TREATING PETROLEUM.

Specification forming part of Letters Patent No. 57.285, dated August21, 1866.

To all whom it may concern:

Be it known that we, D. H. BURKET, of Half Moon, Centre county, and J.G. GRAY, of Putneyville, Armstrong county, both counties in the State ofPennsylvania, have invented cer' tain new and useful Improvements inPetroleum-Agita-tors; and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification.

The object of ourinvention is to produce lubricating-oil from petroleumin a crude state by means of simple mechanical combinations to agitatethe oil, assisted by the introduction of steam or heated liquid into theoil while it is being agitated. By these means the gravity of the crudepetroleum is reduced, which accomplishes the desired result.

The materials used in the construction of our invention are thosecommonly used for accomplishing mechanical purposes.

To enable others skilled in the art to make and use our invention, wewill describe its construction and operation.

In the drawings, Figure 1 is a sectional view of a side elevationthrough the centers of the packing-box, connection, main anddistributing pipes, and the tank. Fig. 2 is a perspective view, showingthe manner of connecting and the relative positions of theagitatingwings and distributing-pipes to the main pipe.

A is the tank into which the crude petroleum is put to be agitated; Inthe drawings the tank is cylindrical but it may be constrncted of anyconvenient or desirable form or size.

B is the cross-bar, for the purpose of furnishing a journal-box andsupport to the main pipe, also to support the standards, which sup--port the journal-boxes for the shaft, through which power iscommunicated from the motive power to the agitator, besidesstrengthening the tank. 0 is the pivot'in the center of the bottom ofthe tank, upon which the main pipe turns; a a, the standards secured tocrossbar B, which support the journal-boxes b b, in which rests theshaft S, driven by a crank, T,

or by a belt over pulley P. On the end of shaft S, nearly over thecenter of the tank A,

is the geared wheel G, which communicates the power from the shaft tothe geared wheel A, which is fitted tightly around the main pipe.

D is the connection-pipe, its upper end being attached to the hose orpipe of the boiler or vessel containing the steam or hot liquid. Itsopposite end fits loosely around the main pipe. On the outside of thisend of the pipe D we make a thread to fit the thread cut in the upperend of the packing-box E, within which and between its sides and themain pipe the packing p, of any suitable material, is introduced. Thelower end of the packing-box is closed. by a nut' or projection, 0,which is firmly connected or secured to the main pipe, and made to fitwithin the packing-box like a piston-head. A thread is cut on theoutside of packing-box E from end to end, or a suitable distance, bymeans of which the packingbox is screwed into the box F by means of thethread inside of it. Box F serves to hold the packing-box andconnection-pipe steady; and by screwing the packing-box into the box Fthe packing is pressed closer. The lower end of box F is made to looselyencircle the main pipejust below the nut 0 on the main pipe. The nut 0prevents the box F from coming ofi.

M is the main pipe. Its lower end rests upon pivot U, and its upper endterminates a few inches above the packing-box and within theconnecting-pipe. The upper end is open and p the lower one is closed.

N N are the distributing-pipes. They are screwed into the main pipe, andboth of the pipes being open at each endthe steam passes freely from themain pipe out of each of the other pipes into the oil. These pipes actas agitators, and we may, if desirable, use one or more pipes. 7

WV W are the wings or paddles, which are secured to the'main pipe. Anynumber that would be convenient anddesirable can be used.

The oil being placed in tank A, connection pipe D fastened to thesteam-pipe, and the band passed over the pulley, the shaft S revolves,and with itwheel G, which turns the main pipe M by means of wheel H, andthe pipe M turns with it wings WW and pipes N N, thus agitating the oil.At the same time the steam forces its way through the pipes D M and N Nout at the ends of the end of the In testimony that we claim the abovewe hereunto have signed our names.
